Answer:
Step-by-step explanation:
Some of your number sets seem scrambled,
I'll do what I can
10² + 24² = 26²
676 = 676 Right triangle
confusion, but probably not
2.4² + 4.5² ?=? 5.2²
26.01 ≠ 27.04 Not a Right triangle
confusion, but probably not
Answer: option C.
Step-by-step explanation:
Given a quadratic function of the form
, if the coefficient <em>a</em> is less than zero, then the function is opened upward.
The options A is not opened upwards, then it is not the answer.
Then the given equation
can be written as:
![x^2+2-6=0\\x^2-4=0](https://tex.z-dn.net/?f=x%5E2%2B2-6%3D0%5C%5Cx%5E2-4%3D0)
This function is equal to the parent function, shifted 4 units down.
Therefore, the graph that you are looking for must be a parabola that is opened upwards and has its vertex in the point (0,-4).
Then, the correct option is C. And the solution is:
![x=-2\\x=2](https://tex.z-dn.net/?f=x%3D-2%5C%5Cx%3D2)
The answer will be 159861
